Hesitation before boosting(NOT 3800RPM)

Ok, i have a new problem on my 88 turboII..
I feel like a kind of hesitation just before boosting and it's not the 3800 rpm hesitation.
I dont know what it can be....I did some vacuum recently.
Can the connection between vacuum souce before the TB, and a vacuum source AFTER the TB do that kind of "problem"?

Is the stock boost control solenoid still connected? If it's capped on unplugged, boost will come in late & low.

Another possibility - When the TPS starts to wear out it can give intermittant closed throttle signals to the ECU.
This video is an extreme example of a really bad TPS.click to play video.

The motor feel the same, its more like it slow down then: BANG BOOOOOST

Maybe its just the feeling of noboost->boost ....
